Carousel ads
Carousel ads are ads with several cards in a row that people swipe through. Each card can have its own photo or video, headline, and link. The first card is what most people see. The rest is extra for people who keep swiping.

What a carousel ad is
Two to ten cards in one ad unit. You can set them manually or let a feed populate them, which is how catalog ads and DPA usually render. Catalog ads are feed-driven ads. Dynamic product ads (DPA) are the personalized version that shows items someone already viewed. Some platforms will reorder cards by performance.
Let's take a shoe workshop in Mexico as an example. They make leather shoes and sell them online to Mexico and the United States. A typical Instagram carousel for the shoe workshop is five cards: a tan leather oxford priced at $189, a loafer, a boot, a close-up of the leather, and a shipping line (free to the United States over $150). Each card links to the matching product page, not the homepage.
When a carousel beats a single image
Range is the obvious case. So is anything that needs sequence: a problem then a fix, three objections then proof. Carousels also let you send different cards to different pages, which single-image ads cannot do.
The tradeoff is attention. Most viewers see card one and nothing else, so treat card one as the whole ad and the rest as an upside for people who lean in.
Let's take a shoe workshop in Mexico as an example. They make leather shoes and sell them online to Mexico and the United States. The shoe workshop spent $5,000 on the five-card carousel and $5,000 on a single image of the tan leather oxford priced at $189, same audience, same three weeks. Carousel click-through rate (CTR: clicks divided by impressions) was 1.6%. Single image click-through rate (CTR) was 1.1%. On the carousel, about 72% of clicks were card one (the tan leather oxford). The other four cards shared 28%. The carousel was credited with 80 purchases ($62.50 each). The single image with 70 purchases ($71 each). The range did a little work. Card one still carried the ad.
How to structure the cards
Put the strongest hook and the offer on card one. If the shoe workshop hid the tan leather oxford priced at $189 on card three, most people would never reach it. Keep visual continuity so a swipe feels like progress (same background, same crop) rather than a new ad. Give each card a destination that matches what it shows.

- Test carousel against single image with the same offer if you want a real answer, not a CTR (click-through rate) comparison across two different ideas.
Common carousel mistakes
Hiding the point on card three is the one the shoe workshop made first: a brand story, then a workshop photo, then the tan leather oxford priced at $189. Almost nobody swiped twice. The shoe workshop moved the oxford to card one and kept the workshop as card five, for the people who were already in.
- Hiding the point on card three.
- Slicing one image into ten cards and hoping people reassemble it.
- Sending every card to the homepage.
